Lunar explorers perform an experiment to understand the size of the craters on the surface of the moon. They layer flour, laundry detergent, and cocoa powder in a pan to model the lunar surface. They drop marbles from different heights...

Encourage your classes to be laundry helpers! Learners explore the chemistry of stain removal with a lab investigation. By identifying the components of the stain, they identify the most effective solute for its removal.

Lesson 21 in a series of 36 specifically focuses on elements and their compounds from groups 13, 14, and 15 on the periodic table — including boron, carbon, aluminum, silicon, nitrogen, and phosphorus. Classes learn how some of these...

In this light worksheet, learners construct a pinhole viewer using a paper box, wax paper, tape and a pushpin. They answer six questions about their observations, the orientation of the images they saw, and the results of their experiment.

For this pronoun usage worksheet, students read sentences with pronoun errors that are underlined and write their corrections. Students write twenty short answers.

A 20-item worksheet calls for learners to write the correct pronoun to replace the underlined one in each sentence. Several of the sentence topics deal with bodily functions, mildly grisly subject matter, and social norms that may be of...

Middle school scientists bathe in Bikini Bottom with SpongeBob and friends. They define steps in the scientific method. They identify independent variables, dependent variables, and the control for science experiments being carried out...

In this chemistry worksheet, students identify the three main phases of matter. Then they search for information about each element on a Chem Time Clock. Students use the chemical symbol to identify each element.

In this marine animal worksheet, 3rd graders study the parts of seaweed. Students label 2 seaweed diagrams and study 24 household objects, circling those that come from seaweed extracts and/or ingredients.

In this Scientific Method worksheet, learners identify controls, variables and conclusions given experiment descriptions. Students interpret data given in charts.
